Added a new serialisation format to support compact internal representations. Compact internal representation of integer sequences. Packages byte-compiled on installation by default. Just-in-time compilation (JIT) of functions and loops to byte-code enabled by default. Support for numeric index values 231 and larger on 64 bit systems. Improved serialisation speed for long vectors. Support for UTF-8 encoding, and the beginnings of internationalization and localization for different languages.Īdding a new compiler function that allows speeding up functions by converting them to byte-code.Īdded mandatory namespaces for packages. Introduced lazy loading, which enables fast loading of data with minimal expense of system memory. S4 methods are introduced and the first version for Mac OS X is made available soon after. The code is hosted and maintained on CVS.įirst versions of update.packages and install.packages functions for downloading and installing packages from CRAN.Ĭonsidered by its developers stable enough for production use. R becomes an official part of the GNU Project. Alpha versions of R for Microsoft Windows and the classic Mac OS are made available shortly after this version CRAN is started on this date, with 3 mirrors that initially hosted 12 packages. This is the oldest source release which is currently available on CRAN. The mailing lists commenced on April 1, 1997. Much of the basic functionality from the “White Book” (see S history) was implemented. This is the last alpha version developed primarily by Ihaka and Gentleman. The R project was conceived in 1992, with an initial version released in 1995 and a stable beta version in 2000Ī list of changes in R releases is maintained in various “news” files at CRAN, but below is a list of milestones: Release
R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, and is currently developed by the R Development Core Team (of which Chambers is a member) R is named partly after the first names of the first two R authors. The R language is widely used among statisticians and data miners for developing statistical software and data analysis. R is a programming language and free software environment for statistical computing and graphics supported by the R Foundation for Statistical Computing. In this article, I want to introduce R, RStudio, Rserve, and how we can pass information from Tableau in R and render the results this is aimed to be an introductory article, and hopefully will give you a good starting point for further exploration.
